Cisco Aironet Directional Hyperlocation Antenna (AIR-ANT25-LOC-02=)
Draft Label—Cisco Confidential
This document describes the AIR-ANT25-LOC-02= antenna and provides electrical specifications and mounting
instructions.
The antenna is a four-port polarization-diverse patch array that operates over the 2.4-GHz and 5-GHz Wi-Fi bands. The
antenna provides both location-based services and Wi-Fi coverage over wide, open areas. The antenna may be mounted
on a wall or mounted using an articulating mount. The location array in the antenna services a wide coverage area (±55º
left and right of the boresight).
The antenna ships with an articulating mount for use on flat surfaces and masts and is adjustable in both the horizontal
and vertical planes. The antenna radome can be painted using commonly available non-conductive spray paints, such
as Krylon or Rust-Oleum. The antenna is designed for use in indoor or outdoor environments. The antenna is designed
for use with the Cisco Aironet AP3702E and AP3702P access points along with the Cisco Hyperlocation module
(AIR-RM3010L-x-K9=).

Safety Instructions
Warning IMPORTANT SAFETY INSTRUCTIONS
This warning symbol means danger. You are in a situation that could cause bodily injury. Before you
work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar
with standard practices for preventing accidents. Use the statement number provided at the end of
each warning to locate its translation in the translated safety warnings that accompanied this device.
Statement 1071
SAVE THESE INSTRUCTIONS
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030
Follow these safety instructions when installing your antenna.
Plan your installation procedure carefully and completely before you begin.
If you are installing an antenna for the first time, for your own safety as well as others, seek professional assistance.
Consult your dealer, who can explain which mounting method to use for the location where you intend to install the
antenna.
Select your installation site with safety, as well as performance, in mind. Remember that electric power cables and
telephone lines look alike. For your safety, assume that any line is an electric power line until determined otherwise.
Call your local power company or building maintenance organization if you are unsure about cables close to your
mounting location.
When installing your antenna, do not use a metal ladder. Do dress properly: shoes with rubber soles and heels,
rubber gloves, and a long sleeved shirt or jacket.
If an accident or emergency occurs with the power lines, call for qualified emergency help immediately.

Installation Guidelines
As antennas transmit and receive radio signals, they are susceptible to RF obstructions and common sources of
interference that can reduce throughput and range of the device to which they are connected. Follow these guidelines
to ensure the best possible performance:
Mount the antenna to utilize its propagation characteristics. This antenna is designed to radiate energy in a
somewhat narrow beam from the front of the antenna. It should be aimed into the intended coverage area.
Keep the antenna away from metal obstructions such as heating and air-conditioning ducts, large ceiling trusses,
building superstructures, and major power cabling runs. If necessary, use a rigid conduit to lower the antenna away
from these obstructions.
The density of the materials used in a building’s construction determines the number of walls the signal must pass
through and still maintain adequate coverage. Consider the following before choosing the location to install your
antenna:
—Signals penetrate paper, vinyl and drywall the easiest. A signal can penetrate five or six walls constructed of
drywall or wood.
—Signals are more heavily attenuated passing through concrete and solid-wood walls.
—Signals often reflect off thick metal walls and may not penetrate at all.
Install the antenna away from microwave ovens and 2 GHz cordless phones. These products can cause signal
interference because they operate in the same frequency range as the access point to which your antenna is
connected.
Choosing the Mounting Location and Brackets
The antenna is designed for use with the Cisco Aironet AP3702E and AP3702P access points along with the Cisco
Hyperlocation module (AIR-RM3010L-x-K9=). The antenna can be mounted only vertically, on a wall, or on a pole. For
pole-mounting, the pole should have a minimum diameter of 2 inches and a maximum diameter of 5 inches (50mm -
135mm).
The antenna is designed for both indoor and outdoor deployments. You can deploy it in large halls, warehouses, and
atriums having high ceilings.
When mounting the antenna you need to assemble the bracket hardware, mount the antenna using the bracket, and
adjust the antenna orientation.
The antenna should be mounted clear of any obstructions to the side or front of the antenna enclosure. Note that this
antenna should be aimed into the intended coverage area, and so you should mount the antenna so as to achieve the
required mechanical tilt. Mount the antenna as close to the access point so that the access point is within the range of
the connecting cables.

The following table lists the materials needed for this installation:
To flush-mount the antenna on a wall, follow these steps:
Step 1 Determine the mounting location for the antenna.
Note The fasteners and mounting surface should be capable of maintaining a minimum pullout force of 150 pounds
(68 kg) to support the weight of the antenna plus the potential wind loading on the antenna.
Step 2 Use the antenna as a template and mark the positions of the holes for flushing-mounting the antenna, on
the wall. Drill holes into this marked positions and insert wall anchors as required.
Step 3 Cut a hole in the wall, for passing the antenna cables through.
Step 4 Hold up the antenna against the wall and pass the antenna cables through the hole in the wall. Make sure
you orient the antenna correctly (note the arrow on the back of the antenna that indicates the top of the
antenna).
Step 5 Align the antenna’s wall-mount screw holes with the holes in the wall, and then fasten the antenna to the
wall using the fasteners which you have procured.
Step 6 Optionally, seal the hole for the cables using a cable sealing system, such as the Roxtec Multidiameter™
cable sealing system. Visit http://www.roxtec.com/ for information on how to install the cable sealing
system.
Step 7 Connect the antenna cables to the access point.
